Abstract
This paper describes a study on the effects of ultraviolet radiation on the development of zebrafish and explains that the study was conducted in an effort to help determine when exposure to ultraviolet radiation can be helpful and when it can be harmful.

From the Paper
"Background and Overview. While global warming represents a threat to humankind by virtue of a reduction in the ozone layer and an increased exposure to ultraviolet radiation in the future (Conscience, Cotton, Schlumpf et al. 2001), researchers have shown that moderate exposure to varying levels of ultraviolet radiation may have some beneficial effects for humans. For example, multiple sclerosis, type 1 diabetes, and, to a lesser degree, rheumatoid arthritis, in the Northern Hemisphere, especially in Western Europe and North America, display a latitudinal gradient in disease frequency, with the prevalence of these disorders increasing at higher latitudes (Lim et al. 2003). Furthermore, ultraviolet germicidal irradiation (UVGI) that occurs in the upper portion of air in a room has been cited as an environmental control measure that could economically reduce exposure to Mycobacterium tuberculosis (MTB) droplet nuclei (Burge, First & Ko 2002)."
